MODEL 209
TALENT CONSOLE
Dante Configuration
For audio to pass to and from the Model 209 requires
configuration of several Dante-related parameters.
These configuration settings are stored in non-volatile
memory within the Model 209’s circuitry. Configura-
tion will typically be done with the Dante Controller
software application which is available for download
free of charge at audinate.com. Versions of Dante
Controller are available to support Windows® and
macOS® operating systems.
The Model 209’s Dante interface is compatible with
the Dante Domain Manager (DDM) software appli
-
cation. Refer to DDM documentation, also available
from Audinate, for details on which Model 209 and
related parameters may have to be configured.
Audio Routing
The Model 209 has two Dante transmitter (output)
channels that are associated with the unit’s Dante
interface. They must be assigned to the desired
Dante receiver (input) channels on one or two de-
vices. This achieves routing of the Model 209’s two
output audio channels to the device (or devices) that
will be “listening” to them. The two Dante receiver
(input) channels associated with the Model 209’s
audio inputs need to be subscribed (routed) with the
desired Dante transmitter (output) channels. These
two audio signals will provide the headphone cue sig-
nals to a Model 209 user. They can also be used in a
TOX (tone operated) mode to control the state of the
tally outputs. Within Dante Controller a “subscription”
is the term used for routing a transmitter flow (a
group of up to four output channels) to a receiver flow
(a group of input channels).
The Model 209 uses an Ultimo integrated circuit to
implement its Dante functionality. The number of
flows associated with this integrated circuit is four;
two transmitter (output) and two receiver (input). With
this small number of flows it’s possible that a flow
limitation condition could occur. A flow can be unicast,
multicast, or a combination of the two. If the Model
209’s Dante transmitter (output) channels need to be
subscribed (routed) to more than two flows it’s pos
-
sible that an intermediary device, such as the Studio
Technologies’ Model 5422A Dante Intercom Audio
Engine, can be used to “repeat” the signals.
Note that when the AES67 mode has been enabled
in the Dante Controller application the Model 209’s
Dante transmitter (output) channels will only function
in multicast; unicast is not supported.
Unit and Channel Names
The Model 209 has a default Dante device name of
ST-M209- and a unique suffix. The suffix identifies
the specific Model 209 that is being configured. The
suffix’s actual alpha and/or numeric characters relate
to the MAC address of the unit’s Ultimo integrated
circuit. The two Dante transmitter (output) channels
have default names of Main and Talkback. The
two Dante receiver (input) channels have default
names of Headphone Ch1 and Headphone Ch2.
Using Dante Controller, the default device name and
channel names can be revised as appropriate for the
specific application.
Device Configuration
The Model 209 supports audio sample rates of 48
and 96 kHz with no pull-up/down options available.
The digital audio data is in the form of pulse-code
modulation (PCM) samples. Encoding choices within
Dante Controller are PCM 16, PCM 24, and PCM 32,
but in most cases the selection of PCM 24 would be
appropriate. Clocking and device latency parameters
can be adjusted within Dante Controller if required but
the default values are typically correct.
Network Configuration
Typically, the Model 209’s Dante IP address and
related network parameters will be determined au-
tomatically using DHCP or, if that’s not available,
the link-local network protocol. If desired, Dante
Controller allows IP address and related network
parameters to be manually set to a fixed or static
configuration. While this is a more-involved process
than simply letting DHCP or link-local “do their thing,”
if fixed addressing is necessary then this capability
is available.
AES67 Configuration – AES67 Mode
Dante Controller allows a Model 209 to be config-
ured for AES67 operation. This requires the AES67
mode to be set for Enabled. As previously noted in
this guide, if AES67 mode is Enabled then the Dante
transmitter (output) channels will use multicast and
their sample rate will be fixed at 48 kHz.
